CALENDAR.

SPECIFICATION forming part 0f Letters Patent No. 387,794, dated August 14, 1888.

Application filed December 12, 1881. Serial No. 47,615.

To all whom z' imag concern:

Be it known that I, HENRY S. HACK, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and use ful Improvement in Calendars, ol' which the following is afull, clear, concise, and exact description, reference being had to the accompanying drawings, in which- Fignre'l is an elevation. Fig. 2 is a crosssection online .fr fr. Fig. 3 is a lengthwise section ou line y y. Fig. et is a detail. Fig. 5 is a modication.

My invention is a novel double-roll calendar, the chief novelty of which is that the bearings for the two spindles which carry the calendar-strip are mounted upon the backing, instead of the two spindles and strip being in a box or case, the spindles extending through the sides of the box, as heretofore.

In that forni of my invention shown in the drawings, A represents the backing, which is shown as formed of a sheet, o, of paper stiffened by sheets of cardboard a2, and finished by the paper sheet o". The other part, a', fornis bearings for the spindles B B', so that when the hacking-Als completed it consists of a backing with bearings upon it for holding the two spindles B B', and the calendarstrip (l extends from one spindle to the other over the surface of the backing, thus forming a new article of manufacture which dilfers substair tially from any other calendar known to me.

l am aware that I am not the first to use a calendarstrip wound on a spindle held in a pair of bearings onabaeking,tl1at being shown in IVatsous Patent No. 190,7(ll, of 1878. I therefore distinctly disclaim all that is shown in IVatsons patent, and also disclaim a dnpliration of Watsons calendar-strip spindle and bearings-that is to say, I do not claim abacking with two or more separate strips and spin dies mounted on its face.

I am also aware that a variety of calendars with two or more rolls have been patented. See, for examples, Poolers Patent No. 77,837, of ISGS, and Kellerls Patent No. 171,227, of 1875. In both of these patents the spindles are in pairs and there is one stri p for each pair ot' spindles. I disclaim, therefore, all that is shown in either of these patents, and in particular disclaim all calendars in which the (No modem strip is in a box or case and that portion only of the strip is visible which is brought under an aperture formed in the front wall of the box or case, for my invention is an improvement upon calendars of this class,consisting in forming two pairs of bearings upon a backing and mounting the two spindles in these bearings, instead ol' making a box or case and mounting the spindles and strip in it, as in Poolers and Kellers.

It is desirable, in order to keep the calendar-strip C close to the front face of the backing, to dedect it as shown in Fig. 2, and this detiection also serves as a tension,

In that forni of my invention shown in the drawings each spindle is mounted in a rel ceiver, D D', the slot in each receiver serving to hold that part of the strip C between them close to the face of the backing. The end of each receiver D D in this form of my invention forms a box or bearing by which the axis of the spindle is kept in a fixed relation with the otherspindle and with the face of the backing, this arrangement of two spindles each mounted in a pair of bearings attached to the surface of a backing by which the axis of each spindle is kept in a iixed relation with the front of the backing and with the other spindle being the chiel feature of novelty of my g improved calendar.

Vhen the part a is of thin paper, it should be strengthened by a slotted tube, d, of thin metal, (see Fig. 4;) but the part a' may itself be of sheet nieta] or of cardboard so strong as not to require the use of tube d. (See Fig. 5.)

The backing A having been l'orined with two receivers, D D', as shown in Figs. l and 2, the spindle'B, having the calendar-strip C wound upon it, is inserted in receiver D and the end of strip C carried out through the slot in receiver D. The other spindle, B, having ashort strip (or a portion of the calendar-strip C) se# cured to it, is placed in the other receiver, D', and the end of its strip is carried out through the slot and cemented to the strip from receiver D, thus making the strip continuous between the two spindles B B. The end pieces, b b', support the spindles and serve to turn them to wind up the calendar-strip on one of them as it is unwound from the other.

I do not claim acalendar consisting of a box,

two pairs oi' bearings in the side of the box, ings being supported solely by the backing two spindles, and n calendar-strip. and that part of the strip lying between the What I do'elaiin as my invention isrolls being uncovered. The improved double-roll Calenda-r above 5 described, consisting ofthe backi1ig,the two spindles, each mounted in a pair of bearings, and the calendar-strip, the two pairs of bear- 1 HENRY S. HACK.
